I recently replaced these. Not too difficult (expensive though, even with a real deal on genuine seals. No aftermarket 86+ available, supposedly). There seemed to be small amounts of weatherstripping glue on the bottom and rear, and much more on the front. Has anyone else done this. What would a professional do? Glue the heck out of it or not? Most of the other seals (top, sides) seemed to use little or no weatherstripping glue.
